Abstract

APARELHO DE PRé-TENSIONAMENTO UTILIZANDO UM PRENDEDOR ROSCADO BIPARTIDO. Um prendedor inclui uma metade de anel circular roscado dividido ao longo de um plano intersectando um eixo longitudinal central. Uma das paredes de extremidade é formada com uma superfície de sustentação de carga, cónica, truncada que é assentada em uma superfície de empuxo, cónica, truncada, formada em um anel circular de um gerador de tensão. As superfícies geradoras de empuxo e de sustentação de carga são arranjadas para apresentar um par conjugado de superfícies cónicas truncadas para prover uma resolução de forças, favorável, desenvolvida pelo torque aplicado aos parafusos de macaco distribuídos em tomo de uma seção de corpo gerador de tensão cilíndrico circundante no sentido para fora.
